Specification of Letters Patent.

Patented Dec. 27, 1921.

Application filed July 20, 1918. Serial No. 245,847.

To all whom it may concern Be it known that I, Louis A. CASGRAIN, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Cementing Apparatus, of which the following description, in connection with the accompanying drawing, is a specification, like reference characters on the drawings indicating like parts in the several figures.

My invention relates to cementing apparatus, and more particularly to that for applying cement to shoes.

In the manufacture of the sneaker type of shoes, in accordance with the usual practice, there is applied to the lasted upper a coating of cement extending over the entire bottom of the inner sole and over the adj acent edge of the upper for the attachment of the outer sole and the foxing, and it is desirable that the edge of this coating along the upper be uniformly spaced from the bottom of the shoe so there shall be visible on the fabric no smears of cement beyond the edge of the outer sole. It is customary to perform this operation by hand, it requiring considerable skill to accomplish it satisfactorily. An object of the present invention is to provide an apparatus by which cement may be distributed quickly and evenly over both the bottom and edge portions of a shoe, with uniformity at the foxing or outer-sole edge, by a relatively inexperienced operator.

A feature of the invention consists in a flexible member movable to bring its side into contact with one of the portions of a shoe positioned by a suitable rest and apply cement to said portion, and then to yield so that its end moves over and cements another portion, thus acting upon both portions. The structure I have found most suitable for this purpose includes a rota table brush having its bristles or similar fibers furnishing the previously mentioned flexible member and extending in the same general direction as the axis of rotation. In coating shoes for foxings, the action of the applying member is preferably such that it first contacts with and coats the edge of the upper, and then yields and sweeps over the bottom portion. A bottom rest is shown, over which the work is guided, the relation of this being such that the applying member extends from one side of the rest to the other and is revolved past it. To vary the position of the band of cement applied, for example to locate its edge on the upper, the relation between the bottom rest and the end of the applying member may be changed, as by adjusting the rest.

A further feature of the invention conerns the provision of a work gage by utilizing for this purpose the edge of the openmg of a cement container delivering to an applyin member movable over and taking cement lTOm the opposite side of the open- Thereby an organization of extreme simplicity and effectiveness is obtained. In the present embodiment of the invention there is at one side of the delivery opening ppposite the gage edge means for adjusting its size, and over this adjusting means the applying member preferably moves.

I may employ for the cement-applying means a device, as a brush, in which the flexible members contacting with the work consist of groups or tufts of fibers spaced from one another. With such a structure I prefer so to separate the members that they will not interfere with one another in their yield. The applying members cooperate with the other elements of the apparatus in a novel manner, with the work gage, for example, causing the cement, when cementing for foxings, to enter fully the angle between the work and gage, insuring a uniform edge.

The above and other features are illustrated in the accompanying drawing, in which, 4

igure 1 is a perspective view of one embod ient of the invention, parts being broken away;

Fig. 2 is a horizontal section taken on the axis of the brush; and

Fig. 8 is a partial side elevation with portions in section, illustrating particularly the cement container and the cooperation of the brush therewith.

Journaled in standards in a frame 10 is a shaft 12, at one extremity of which is carried an applying device preferably furnished by a brush it. This brush may consist of a head 16, conveniently in the form a disk of wood, the head being held by a 1 20 against a shoulder formed by a reduced portion 18 of the shaft. From the outer face of the head near its periphery and in a direction generally parallel to the axis of the shaft, though here shown as somewhat inclined outwardly therefrom, are groups or tufts of some such flexible fibers as bristles. These groups appear uniformly spaced circumferentially of the head, being separated by such a distance from one anther that when they are bent in the cementing operation, the adjacent groups will not come into contact. The advantage of this will later appear. The shaft and brush are rotated from any convenient source of power through a pulley 24: so secured to the shaft that they turn together.

About the brush, supported upon the frame, is a casing 26 to retain cement which may be thrown off in the rotation of the parts, this casing being provided with a removable cover 28, giving access to the brush. Atone side of the casing is an opening 30, through which the bristles carrying the cement come in contact with the work. Carried upon the frame near the upper edge of the openingSO is a cement container, here shown as furnished by a receptacle 32 of such size as to contain the desired quantity of cement. At its bottom the container narrows to a contracted throat terminating in adelivery opening 34, the size of which, and therefore the quantity of cement flowing, is controlled by a gate or like member 36, which is illustrated as sliding over the inner face of the rear wall of the container. The brush is so located that the ends of the bristles move over the container wall and then across the gate and opening. They are somewhat flexed by this contact, and when released at the lower edge of the gate tend to assume their normal positions and thus throw the cement toward a gage 37. This gage I preferably furnish by the wall of the container or passage therefrom at the opposite side of the delivery opening from the gate 36. With it the work contacts to define the margin of the coating applied. Since the groups of bristles are wholly out of contact with one another when bent, each group in delivering its cement at the edge of the gage is free to enter the angle between said gage and the work in a nearly straight position, so, with the impulse applied to the cement as just described,the entire surface of the upper adjacent to the gage is uniformly coated. As the bristles wear in use. it is desirable to have means for adjusting the relation between their ends and the gage portion 37. This is preferably accomplished by a screw 38 threaded into a bore in the end of the shaft 12 oppo 7 site the brush and having outside the frame a nut and lock nut 40, between which and the frame is interposed an anti-friction washer 42., The washer is forced against the frame to carry the brush toward the gage for any particular adjustment of the nuts, by a spring 44 situated at the bottom of the bore and contacting at its outer end with a key 46 passing through a slot 4:8 in the shaft and being driven into an opening in the hub of the pulley. The key and slot compel the rotation of the shaft with the pulley, while permitting the independent longitudinal movement of the former.

To furnish a support and guide for the work so it may be moved in the proper relation to the gage 37, there is a rest 52 sit uated upon the opposite side of the gate 86 from the gage, with the groups of bristles moving past the rest and their ends extending beyond it. This rest is shown as in two portions connected by a yoke 58 extending over the throat of the container so that 'a somewhat extended supporting surface is presented to the work. It may be adjusted toward and from the gage to vary the width of the strip of cement applied to'the upper by a screw 54; passing through a slot in a shank 56 of the gage and into the frame. To assist the operatorin moving the work regularly past the revolving groups of bristles, I provide feeding mechanism, including a bell-crank lever 60 fulcrumed at upon the frame. This lever has near the end of one arm an anti-friction roll 64 conof the pulley 2%. A plunger 68 movable in a recess in the inner side of the casin 26 to v and forced toward the lever by a springi'b maintains the roll 64; in contact with the cam. The opposite end of the lever has pivoted uponeit at 72 a feeding detent 7 1-, the serrated end 76 of which contacts with the work in successive reciprocations of the lever by the cam. This tends to urge the work step by step across the rest for the application-of cement by the bristles. Upon the outward movement of the detent to avoid feeding in this direction, it may yield against a spring-pressed plunger 78 seated in a recess in the adjacent end of the lever 60.

In employing the apparatus for cementing a lasted shoe, as indicated in section at S in Fig. 3 of the drawings, the bottom of the shoe is placed against the rest, and, the shaft 12 being in rotation, it is advanced over said rest and beneath the delivery opening of the hopper by the operator, aided by the action of the feeding detent. The successive groups of bristles in their revolution, passing across the opening in the container in the direction indicated by the arrow in Fig. 1, carry the cement, as pre viously described, fully into the angle be tween the gage and the upper. coating this portion of the work first by the contact of their sides with the upper, and then yielding so that the ends of the bristles pass over the edge and across the bottom of the innersole past the longitudinal axis of the shoe. As the Work advances, this operation continues about the entire periphery of the upper the coatings from opposite sides upon the bottom meeting and overlapping at the center so that the innersole is completely coated.
